This inventionrelates to an improved well casing or tubing holder and elevator.

Ihe-primaryobject of this invention is the provision'ofanimproved mechanism prefer ably adaptedto housed in connection-with oil Wells for the eflicient" holding of well pipe, such as casings and j tubing in order to support the pipe efliciently upon the well plat- 7 form, or permit the elevation of the tubing in connection with-aconventional elevator mechanism. v

A -further" object of this invention isthe provisionfof an'improved type ofwell casing support, embodying a-novel t-ype 'of'jaw mechanism embodying a: plurality of'jaws which operate in unison to uniformly grip the casing circumferentially 'thereabout, where: by obviating eccentric well casing support action, as is caused by conventional casing supporting mechanism.

A further object. of this invention is the provision of a relatively simple operable type parts throughout the; several views, 7

Inthe drawings, wherein for the purpose ofillustration is shown aipreferred :embodi inent ofthis-construction and means by which the sameinay be used eitherlas acasing support upon the well platform or as an elevator, the letter A may generally designate'the improved pipe holder and elevator, which may comprise a supportingbas'e B, having novel a aw structures Gmounted thereon, preferably four in number, being connected forsynchronous opening and. closing, by means D. Operatin 'means E is'provided for manually causing t "eopening and closing of the jaws in cooperation with the means'D. The means F maybe provided for connecting with the base B-when the device is being usedfas an elevator'for wellcasing and tubing.

The baseB-is relatively heavy, preferably being madeofmaterial suitable to withstand ing the-strains and forces placed thereon incident' to "the holding and elevation of well casing-and tubing,'as=will be understood by crrY, OKLAHOMA, AND;

those-.skilledinthe art to which this inven tion rel-ates. The base B in the plan view is preferably polygonal form, somewhat in the nature .Of-fi; 'squarewith'the corners 'thereof'r-em'ov'ed to provide -the bevel edges 20, ad jacent which the four jaw structures have their pivotalconnectionf; The base '13 centrally thereof is provided with a ,prefera'bly circular opening 21 thru which the upper end of a tubing. .or casing -K extends, as is illustrated 'in'Figure Z ofthe drawings.

Referring to the jaw constructionsthe same are-each identical, and eachof'the same is provided with-a preferably integral bearing 2-2 atone of the-corners'onthe base B, being raised 'fromthe norm-al top surface '23. of the base B4 Eachbearing 22 is provided with a sOcketopeningQe, thru which a transverse pivot pin 25 eX-tends',"to pivotally'connect the lower endof'ajaW supporting link 26. The

jaw supporting link 26 is best illustrated in perspective in Figure 6 of the drawings, having a lower widened end 27 provided with a transverse opening 28 to receive the pin 25 above mentioned. At a distance above the 34, provided with a transverse opening 36 therein parallel to the opening 28 above mentioned, adapted to receive a pivot pin 37, mounted on one of the jaw members 38, in order to connect the latter thereto for oscillation thereon. p

The construction of each jaw member 38 is well illustrated in the various views of the drawings, as including a transversely concavo-convex or segmental body 38 providing a liner receiving concave face 42 and a convex outer face 43. Onthe convex face 43 is disposed a radial link connection 44, which provides an outwardly disposed socket 45 therein adapted to receive the shank 34 or the connecting link 26 above mentioned, The side walls of the extension 44 are apertured at 47 for receiving the ends of the pin 37 which as above mentioned is used to pivot the jaw member 38. The pins 25 and 37 are both detachable, and are in the nature of rivets of approved formation.

The jaw bodies 38 are of course concentric,

in so far as the arrangement on the device is concerned, and are always arranged in annular relation, to provide a passageway which is truly circular for receiving a casing or tubing K. Each jaw 38 receives a detachable liner 50, on the concave face 42 thereof. Due to the extreme forces placed thereon the liner 50 is of an exceptionally durable metal construction, and includes the concavo-convex segmental body portion 51, adapted to fit into conformity over the concave surface 42 of the jaw member 38; it being understood that in width the liner-50exactly conforms with the curvature of the body 40. The liner body 50 at the top thereof is provided with an overhanging flange 53, which overlies the top surface 54 of the body 40 of the jaw member 38, to serve as protection for the jaw body portion, and toserve to anchor the liner onto the jaw body. As an additional means tosecurely and effective- 1y connect. the liner to the jaw body 40 the said top wall 53 is provided with a depending lug 54 extending below the normal bottom surface 55 of the flange 53, which is adapted to seat within a recess 56 formed inwardly of the top surface 54 of its respective jaw body 38, as illustrated in Figure 8, to maintain the liner 50 in position on the jaw body 40 against circumferential movement. As a means to limit longitudinal movement of the liner 50 with respect to the jaw body 40, a depending flange 56, preferably contiguous with the lug 54 is suspended from the wall 53, beyond .the outer surface thereof, adapted to fit over the outer surface of the jaw body 40, the same having an opening 59 therein to align with a screw threaded opening 60 transversely thru the body 40, to receive a detachable screw 62 illustrated in Figure 2 of the drawings, to retain the liner in non-movable relation upon the jaw body, as can be understood fromthe drawings. The inside concave surface. of the liner 50 is provided with a toothed surface 66, illustrated in Figure 2 of the drawings, preferably tapered upwardly in order to effectively grip the tubing or casing K to prevent the same from slipping downwardly thru the jaw construction.

Referring to the means 1) for maintaining the uniformity in operation of the jaws, each jaw member 38 on the external surface 43 of the body 40 thereof, adjacent each of the side edges thereof, is provided with upper and lower apertured 1ugs70 and 71. WVhen the jaws 38 are in position, the upper apertured lugs 7 O of the facing sides of adjacent jaws will have the axes thereof in aligning relation, for receiving bolts or guide pins 74. The guide pin 74 for each pair of aligning apertured lugs of adjacent jaws, is rigidly connected in an adjustable relation with one of the lugs, and slidably extends thru the aperture of the other lug. Thus, as is illustrated in the various views of the drawings, the guide pin or bolt 74 is provided with a screw threaded shank which extends thru one of the lugs, having lock nuts 71 and 7 2 at oppositesides of said lug 70. The smooth end of the shank of the bolt 74 extends thruthe aperture of thevother lug 70, l

as is illustratedin Figure 4 of the drawings, and the head of the bolt 74 serves to prevent the bolt from being removed from the aperture of the last mentioned lug 70. Thus, it is apparent that each of the jaws is connected at the upper and lower end thereof by means of the guide bolts 74 to the upper and lower ends of the adjacent jaw, to insure that all of the jaws will open and close in an exact concentric relation.

1 The jaw-structures C are pivoted in diametrically opposed pairs, by means of the links 26, so that it is apparent that upon lifting upwardly on the link 26 of one jaw, and due to the guide pins or bolts 74, the other jaws'will likewise be lifted upwardly and moved outwardly concentric with the other jaws. V V

Referring to theoperating means E, the

treatise same i cl d s a aft-SOrPi Qta Iy suppo ted Figure 9 is provided with a throw portion 88,

to which is pivotally c'onnected a" link 89-; the opposite end of said link 89 having-a connection at 190 to thejaw link 26, immediately thereabove, adjacent; the outer end of" said -j aw vlink 26; sothatit is readilyeapparent upon oscillation (of the shaft -80,/that the link "26 will be alternately elevated and lowered, ,due to the link and c throw portion connection, to elevate; and lower the jaw memT ber;38.; The lever handle 83 is providediwith a c.onnectingrod 95, pivotally connected at. .96

thereto, which Y extends .-tr ansver sely across the base, jpreferably att right angles .to the shaft 80, and at its opposite endiconnected to an arm. 97 of-a second I shaft; 98, which .is pivotally supportedon bearings 99 and lOQ beneath the link 26 ofa jawstructure which is diametrically opposed from thejawstrucv ture beneath which the first mentioned shaft is mounted, The shaftf-98 ismounted e2;- actly parallel to the shaft;8Q,'and intermediate the ends thereof thielsame has a throw portion 103, illustrated in dotted lines in Figure 1 of the drawings, and also illustrated in Figure 3 of the-drawings, which throw portion is connected to alink 104 which in turn is connected at 105t0 the 'aw'connected link-2 6 immediatelythereabove; ,It is read"- ily apparent that'upon swinging of the lever 83, both shaftsl80 and 98 will1be simultane-c ously rocked to simultaneously elevate or lowerthe ja'w links 26 respectively thereabove, and to consequently cause a proximate or remote movement of'thejaw members 38 which are respectively connected thereto. It is not necessary to place operating lever means below the other two j aw constructions, si cefdue to the meansD above described all of the jaws will be operatedin unison ,,to uniformlyand concentricallyexpand or contractLwi-th respect to a casingior tubing which may be received therethrough; a

.In the application of the casing holder upon a welli the base B, isof course rested upon the platform, fcasin g,; or any other suitable location where thefisame can support the well casing orztubing-K in the desiredrelation; It isflat once. apparent, since the links. 26 I diverge upwardly, at ,an angle t'ojthehorizontal, on which the baseiB rests, that due to the weight of the casingK, the jaws 38 will have a clampinga'ction upon the casing which increases proportionate 'to the weighttof the casing. J I f rde r easet a ns-it mer y- Thesh-aft 80 at oneen-d thereof necessary forzthe 'operatortto swing the: lever 83 from the position illustrated in FigureLZ of the; drawings, away from the well casing K received n-rbetween -the,;jaws 38, andthis' will move the jaws 38;-away from each other, concentrically anduniformly away from the casing K-in orderto release the latter.v t

' Aszabove mentioned the: improvedcasing holder; is adaptable: for use-was "an elevator. To thisend, gtheba'se Bisjprovidedwith upstanding connectingears 110, at diametrically opposed sides thereof, having horizontal socket-slll therein, open horizontally outwardly at the outer sides-0f the base B. The sockets 1 1 l are adap tedto receive therein the hook-shape d ends: 112 of suitable elevator reins or rods 113, illustratedin igure 7 ofthe vdrawings, which aresuitably connected; to acable hook orvcoupling lli'. v The rods-i113 extend upwardly from the ears n a rei'gi s re a o wa the ceup n 151 4. InjQrder to, retain the hooks 112-in :the socket openings; 113, suitable filler pieces 116 are provided forfittingin the socket open, ings 111, at the outer sides of the hooks 112 when received therein ;1 the fillerqpieces 116' being. apertured forthe reception of detachable bolts orscrews 117, which engage trans versely thru the ears 11 0:across.the socket 111, as is illustrated in Figure To-f, the drawlIlgS. p I v t From the;foregoing .description ofthis in vention it is apparent that a novel ftype of w ell casing holder, support, and elevator has beenprovided, which will efiicientlysupport the casingin anev'enlyclainped and durable manner, against liability of accidental slipping ofthe casing, or disconnection thereof. The ease with which the jawconstruction may operate is a commendable feature, since it merely necessitates i the intervention of, a

single operatorinorder to operate all of the j aws',"a'nd this is contrary to conventional practice where clamping slipsare used, to support casings, which in themselves provide a very unsatisfactory and eccentric grip on thewell' casing, and require the combined I efforts of several persons'in order to connect or disconnect. I y a I Various-changes in the shape, slze, and arrangementof'parts may bemade to the'form of invention herein shown and. described,
